Mastodon Diff Tool

[maarzt]

This is part of mastodon-sc/mastodon-git#12

Develop a tool that can display the differences between two versions of a mastodon project.

It should be able to display the following things:

• spots added / removed
• links added / removed
• changed spot id
• changed spot label, positions, covariance matrix
• display changes in tags

It's maybe feasible to ignore things like: gui settings, computed features etc.

This tool should be able to produce a human readable output as well as a machine readable ".mastodonpatch".

The tool should also be able to apply the machine readable ".mastodonpatch" to a mastodon project.

TODO

• [ ] Data structure that contains insert, delete and update operations for spots. The update operations should lead from version A to version B
  • [ ] List with inserts
  • [ ] List with deletes
  • [ ] List with updates
• [ ] Use git graph, to differentiate between spots that need to be updated or inserted/removed
  • [ ] Spot existed on last common commit of version A and version B leads to an update operation
  • [ ] Spot did not exist on last common commit of version A and version B leads to an insert operation
  • [ ] Spot existed on last common commit of version A and version B and does not exist anymore leads to a delete operation
